Claims. (01. 98-94) The subject matter of the present invention reposes in a ventilator structure, casement windows or doors, and/or windows or doors of the type having lightsor sections of glass divided by mullions or the like running vertically, horizontally, or in both directions.

Much emphasis is being directed at the present time to the subject of ventilation, particularly of residences and the like; also casement windows and such like are increasingin popularity, espe cially in residences. Heretofore much concern has been givento the problem of equipping a casement type window, or a window with mullionbars with a ventilator. Particular reference is made i to a-ventilator having a fan and an electric motor for operating the same. It is believed that up to the present time no satisfactory arrangement has been devised.

.The'present invention aims to provide an ar- I mullions usually embody also a casement type of I Fig. 3 is a vertical sectional view taken through the ventilator window andportions of the building structure. v ,7 V

Fig. 4 is a horizontal sectiongtaken substantially on line 4-4 of Fig. 5. I Fig. 5 is an enlarged ,insideview of a portionof a window and illustrating certain details of structure. n w I i I Fig. 6isa vertical section through the ventilator illustrating structural features and showing how the motor and fan may be mova bly mounted, Fig. 7 is an inside view of the ventilator fram with motor and fan removed. I I I Fig. 8 is a small view illustrating 'a portion of; a window on the outside. without a ventilator moun ed t re n.- 1

First referring to Fig. 1, the particular window shown has a frame I and a plurality of lights or sections .of glass 2 divided by vertical mullions 3 and horizontal mullions 4 and the framev and mullions may be of metal such as steel with the glass panels sealed in any well-known manner with putty, lead or other suitable sealing material or cement. For the purpose of convenience the term ffputty will be. used largely herein and this is'to be. construed broadly as a Wordcovering any material suitable for the purpose. The windowmay have a casement section which consists of a frame 5, horizontal mullions 6, and vertical mullions ldividing the glass panels, which section may be hinged as at 8- so that thesame may be opened. This figure shows a ventilator generally, illustrated at H] mounted on the upper portion of the Window with lights or glass. panels .I i on either side thereof. Withoutthe provision of the ventilator. the window would have, in: stead of small lights I I, two lights identicalwith the lights or glass parts 2 divided by a-vertioal v those seen in Fig. 1, The invention may be carried outby installing the ventilator in a'window frame which originally was not so equipped, in which event one of the mullions may be removed, asfor example the center uppermost mullion 3a assho wn in Fig. 8. Likewisethe glass panels; 2 on either sidethereof may be removed, and then the ventilator installed and. the smaller panels ll installed if the same were necessary. The invention may be carried,- out by originally equipping a window with a ventilator.

Refer now to .Fig.; 3; Certain structural details of the building are shown, as for example, the brick l5, stone l6, these being on theout side, and on theinside plaster H and sill. I8. The frame I which in cross section may'approximate a Zshape is suitably fastened in posi tion and itmay be sealed by a suitable putty or mastic l9, and a metal strip Zll may be applied to drain oft the water. The frame 5 is illustrated in closed position with the glass panels 2 cut through to shorten the view, and after the usual fashion, the glass is sealed in by putty 2]. The ventilator passageway may be provided by two telescoping members the inside one being of apertures.

fastened to frame member la by screws or the like 29. These screws pass through apertures in the frame and may thread into bosses 30 on the frame member.

Refer now to Fig. 4: It will be seen that the frame member 25 has a flange 3| on opposite sides and also preferably has the flange-like part 32, the two flanges cooperating to form an L- shaped panel. The mullions 3, as shown in Fig. 4,

may be T-shaped in cross section; accordingly, the parts 3] and 32 constitute what may be termed half a mullion. The member 25 has a central aperture extending therethrough bounded by walls 33. p

The other member of the ventilator is illustrated at 34 and it may telescope withmember 25 and this member also preferably carries openable closure members or louvers 35-whi'ch"are" closed as shown in Fig. 6 and at least partially open as shown in Fig. 3, and which may be opened and closed by means of a lever 35 through mechanism which is not shown. a The fan is shown at 40 mounted on a shaft of motor carried on a frame 42. The frame may be pivotally connected to the member 25 as at 43, and it may be detachably connected at'a point diametrically opposite the hinges 43 by means of a thumb screw 44 (Fig. 3 -A screen-45 carried by airing 46 may cover the motor and fan and it may be secured to the member 26 "by thumb screws 41 (Fig. 5). An electrical switch for controlling the operation of the motor is" shown at 48 (Figs. 4 and 5). The two members 25 and 34 may be secured. together as by means of'screws EUadvantageously locatedoutside of the central passageway as illustrated in Fig. 5, passing through the member 25 and into internally screw-threaded bosses 15! carried outside a tubu- 26 may be circular forfitting over the central circular portion of member 25 while the outer end carrying the louversmay be rectangular or square. The members may be drawn together by the screws until flange 53 of member 2-5 butts against member 34, as-"illustrated inFig. 3.

Let it be assumed that a-window, such as shown in Fig.8, is already installed in a house. and it is desired to equip the same with a ventilator. The mullion 3a may beremoved, preferably after having first removed the glass panels on either side thereof. The mullions are usually separate pieces having their parts interfltting withjthe horizontal frame members or mullions. The-only modification needed in the frame is the provision Two of them may be drilled through the frame member I on centers de signed. to take the screws 21; two apertures may be drilled through the frame member la. de

1 signed to receive screws 29. The ventilator may now be located and toseal the same, put ty or the like maybe used, as illustratedifi Fig.- 3, and then the screws 2! and 29 are positioned. Thus by these simple expedients the ventilator structure is mounted in the window frame. The glass panels ll may now be inserted;- these may be cut from the glass previously removed-or brought to the job by the workman if he knows before hand what dimensions are needed. iThe glass panels II maynow be inserted as-shown in Fig. 4, each being held on one vertical "edge move a mullion strip to secure the ventilator in the frame and then glaze'the' frame on opposite sides of the ventilator.

The present disclosure shows the ventilator mounted in a portion of a window which is not hingedly mounted. It is entirely feasible, however, to mount the ventilator in a hinged frame and this will be readily appreciated by reference to Fig. 1, where it will be seen'tnat the ventilator may be mounted, for example, in the upper section of the hinged section by removal of the up-' per mullion I, the upper glass panels on either side thereof, and then the mounting of the venti later and smaller panels iihplace. The structure is of. a compact nature and the motor may lie inwardly of a vertical plane coinciding with the face of the plaster I! so that a window shade may be readily lowered without interference by the ventilator structure or the motor: I

Inuse, theventilator may be controlled-by the 7 switch. 48 carried by the ventilator'framefiand the louvers may. be opened and closed by operation of the lever 36. The louvers maybeopened with orv without motor operation. "Access may easily be had to all parts for: cleaning as'fol-f lows: by removing the thumb screws 41' the screen maybe taken off and then by loosening thumb screw 46 the motor and fan rn'ay' be swung, to a position. as shown "in, Fig. 6 "which af fords access to the passageway, the louvers and thefanitself.
